Writing my own alerts in Home Assistant from Purple Air's data since Environment Canada uses the 1 hour average for PM25 and that's way too slow for how sensitive I am to these wildfire smoke events.

This grabs the raw PM25 data from Purple Air (both real time and the 10 minute average, using a Home Assistant REST API sensor) for the sensor closest to my place and calculates the US AQI value (which I like better as a scale). If it, or the Environment Canada AQHI reading is elevated (US AQI > 75 or CA/EC AQHI > 2.9) it sends me an alert.

The notification gives me the environment Canada AQHI with the US AQI based on Purple Air's 10 minute average, and the trend based on the 10 minute AQI minus the Real Time AQI

I think the most annoying and disturbing discovery about this temporary no internet run is the fact that my fucking #Eufy cameras are useless without internet.

I bought a bunch of em, eventho they're a lot expensive than other cheap alternatives from #Tapo/#TP-Link and #Xiaomi bcos they're "supposed" to be offline and not connected (or at least, not reliant) to the cloud, yada yada, but quickly after I bought them, despite that being their marketing for the product - they were called out in multiple occasions that that's just not true.

Anyway, yea, from last night till ~2pm today, it's been recording fuckin' nothing. Bloody hell, please, avoid Eufy and #Anker products at all cost. After I got into #HomeAssistant, and doing more research on security cam products, #Reolink (and Tapo) seems to be where it's at and what you should actually get.

If you plan to use a Midea with #HomeAssistant, don't bother pairing Matter. Your heat mode will be missing, and BOY HOWDY do the two get mad at each other. Instead, get Midea AC LAN from HACS. Then set up the unit with the Midea SmartHome app, and use that to set up MIdea AC LAN in HA. Then just uninstall that app and forget the account exists cause HA has the keys and talks to it directly.

Ah, this aircon is so much quieter! And it's reversing, ie - has a heat mode! Heat mode only works down to 41 degrees F outdoor temp. So, I got an automation in #HomeAssistant that triggers when the outdoor temp is within 2 degrees of that cutoff AND if it's heat mode, that will read what I had it set to, copy it to the electric resistive heater, and then shut off the heat pump window unit.
It's Oregon. It doesn't stay that cold for all that long.
The rest of the time, it does full auto!

Hello #homeassistant geeks (more specifically #esphome geeks). I'm facing something new: I need to control some appliances (4 motors and 1 light) with Home Assistant. I was povided with a couple of pricey RF 433mhz remotes that I really don't want to disassemble (so I cannot just solder some bodge wires to the keys pads and connect them to an #ESP8266 ). I need something that can receive, copy and re-send the signals mimiking the original remotes. I don't know anything about RF, don't own an SDR and don't know if the remotes use some kind of rolling code. I've seen there is some support on ESPHome for 433mhz transmitters (https://esphome.io/components/remote_transmitter.html) but it's unclear to me with what hardware.
Anyone can point me in the right direction?

More details…

It’s very simple device. You can set the temperature in #HomeAssistant or on the device with the wheel.

The temperature sensor is not exposed as sensor, so I had to create a helper in HA.

We will see how it’s going to operate during winter, but I have already ordered standalone temperature and humidity sensors for each room to make it more accurate.

I have some issues to iron out, but having #HomeAssistant add to my to-do list when a battery goes low, and include the battery type, is handy. Same happens when my servers have updates.

Now, if only my AuDHD ass could remember to look at my to-do list.
